Abstract
Device for determining the relative position of two or more catheters in the human body, there being disposed on each catheter (4, 5), preferably in the area of the catheter tip, at least one measuring electrode (ME1-ME8; ME9, ME10) which can be connected to a voltage source together with one or more measuring electrodes of a further catheter, wherein the resistance between the measuring electrodes, and hence the distance of the measuring electrodes, can be determined via a current measurement.

9. A device for determining the relative position of a first and second catheter in a human body, comprising:
-
a first measuring electrode arranged on the first catheter;
a second measuring electrode arranged on the second catheter, the first and second measuring electrodes configured to be connected to a power supply unit, the power supply unit configured to be connected to at least a third measuring electrode of a third catheter; and
a measuring unit for determining an electrical resistance between the first and second electrodes by measuring an electrical current flowing through the first and second electrodes and for determining a distance between the electrodes based on the determined electrical resistance, wherein the relative position is determined using the determined distance. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
